2.0 Drive mounting and configuration

2.1 Handling and static-discharge precautions

After unpacking, and before installation, the drive may be exposed to
potential handling and electrostatic discharge (ESD) hazards. Observe
standard static-discharge precautions. A grounded wrist-strap is preferred.
Handle the drive only by the sides of the head/disc assembly. Avoid
contact with the printed circuit board, all electronic components and the
interface connector. Do not apply pressure to the top cover of the drive.
Always rest the drive on a padded antistatic surface until you mount it in
the host system.

2.2 Jumper settings

2.2.1 Master/slave configuration

You must establish a master/slave relationship between two drives that
are attached to a single AT bus. You can configure a drive as a master
or slave by setting the master/slave jumpers, shown in Figure 2 on page
18.
These drives support master/slave configuration using the cable select
option. This requires a special daisy-chain cable that grounds pin 28
(CSEL) on one of its two drive connectors. If you attach the drive to the
grounded CSEL connector, it is a master. If you attach the drive to the
ungrounded CSEL connector, it is a slave. To use this option, the host
system and both drives must support cable select, and both drives must
be configured for cable select. To configure this drive for cable select,
install a jumper as shown in Figure 2.
For the master drive to recognize the slave drive using the DASP– signal,
the slave drive must assert the DASP– signal at power up, and the
master drive must monitor DASP– at power up.

2.2.2 Alternate capacity jumper

Some older computers may "hang" if their BIOS detects a hard drive that
has more than 4,092 cylinders at startup. To allow these computers to
recognize the ST317240A, ST313030A, ST310231A, ST38420A or the
ST34310A, these drives include a capacity-limiting jumper, which sets
the drive's default translation geometry to 4,092 cylinders. This limits the
drive's capacity to 2.1 Gbytes, unless third-party software is used.
